I don't think you'll have high enough light levels for most things . The best window for indoor crops are on the south side, but even there winter light levels are generally too low without adding some fluorescent to supplement it . My guess would be you'd have more success with green crops like lettuce, spinach or swiss chard than you would with root crops; but would still need to use added fluorescent to make up for the lower winter light intensity.

My suspicions have been exactly like Dave suggests.............that there is not enough light in the winter time. Even more so in the Okanagan where the valley is socked in pretty much the whole winter.

But I thought I'd ask to see if anyone had any bright ideas. Thanks again.
